Patented May 5, 1931 STATES CHARLES L. ANDERSON, OF RAYENSWOOD, WEST VIRGINIA BROOIDER l Application filed April 23,

My present invention relates to chicken brooders, and especially to a stove for such brooders in which gas burners are employed for heating the same.

The primary object of the invention is the provision of a brooder in which the intensity of a flame from a gas burner may be regulated to a nicety, and in which no unburnt gas will escape to the brooder chamber, and

whereby chicks hovering in the brooder will be effectively warmed without necessitating the crowding up so closely as to kill the weaker chicks and without danger of the sweating of the chicks by too closely crowding.

A further object is the pro-vision of a brooder for baby chicks that is heated preferably by natural gas although artificial gas may be employed, and wherein the burner for the gas is disposed in a cylindrical cham- 533 ber at a point above the height of the chicks,

the said chamber below the burner having an apertured partition therein, and the chamber itself, below the partition, being apertured, so

that through these apertures warm air may flow to thoroughly ventilate the brooder.

A further object is the provision of a brooder in which the gas burner employed is of a particular and peculiar shape and has associated therewith an air mixer as well as 39 a means for controlling the flow of gas to said burner, the said burner being arranged in a cylindrical casing whose lower portion is apertured, above an apertured partition in the said chamber, the top of the chamber being formed with a removably secured valve controlled outlet stack as well as a normally closed opening whereby the draft in the chamber may be controlled, and the said chamber having likewise removably secured thereon 49 a protective shield or canopy for the chicks which hover in the brooder.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawings:

Figure 3 is a similar sectional View approximately on the'line 33 of Figure 1.

these apertures there is fixed in the casing i partition 4 whIch:1s also provided with aper tures 5'. The top of the casing is flared. or inclined. inwardly, as at 6,.and merges into: a neck portion 7 to which there is preferably removab'ly secured a flanged cap 8 that forms the closure for the casing. The top or closure"8 is provided with an openingsurrounded by an extendingpipe or stack 9 and the passage through the stack is controlled by a hand operated damper 1-0. The top 8 to one side of'the stack has another opening 11 there through and this opening is normally closed by apivotally supported and, therefore, swingable' plate 12. The opening 11 is designed to permit of the user of the device observing conditions in the casing 1', most especially with respect to the flame of the burner in the casing which will hereinafter be described. p Leading through the floor 2 of the brooder to one side of the casing there is a gas inlet pipe 13. Screwed on this pipe there is a nipple thatin turn is screwed on one branch of'a valve casing 14. The nozzle end of this casing is for distinction indicated by the numeral 15 and the passage through the nozzle is controlled by a hand operated needle valve 16'. The stem of the valve 16, of course, passes through a suitable packing box that is screwed on the casing 14. and the casing directly inward of the nozzle is also formed with exterior threads on which there is threaded the outstanding cylindrical flange 1-7 of mixing chamber 18.

The'chamb'er 18 has both of its sides provided with rectangular openings 19, through which atmospheric air is admitted. The casing 1 is provided with an opening 26 disposed above the gas inlet pipe 13 and through this opening a light-ed match is designed to be passed for lighting the gas from the burner 23.

There is freely received in the mixing chamber 18, but held thereto by a binding e1ement20, the inner and straight end of the inwardly flared pipe member 21 and in this pipe member there is screwed a pipe 22 which in turn is screwed to one end of a split but cylindrical burner 23. The fuel apertures 24 in the burner 23 are upwardly directed with respect to the casing 1.

Removably arranged on the top of the casing 1 there is a shield or canopy 25.

With my improvement it will be noted that the heat is upwardly directed through the casing 1, and is radiated therefrom into the surrounding space. The canopy 25 need be employed only under certain weather conditions and obviously the base or floor 2 may be 25 surrounded by a flange so that the same provides a hover of a box-like construction in which the chicks are arranged. The particular and peculiar arrangement of the needle valve which controls the flow of gas to the burner, the particular construction of the burner and the particular construction of the mixing chamber are important features of this invention but the arrangement of the stove or casing with its damper controlled gas and combustion outlet, its observation inlet opening and the removable shield or canopy arranged thereon are also important features of the improvement.

Having described the invention, I claim: A brooder comprising a cylindrical heating chamber arranged in upright position, the chamber having an upwardly tapering top and a cylindrical neck upstanding from the top and surrounding an opening therein, a cap as of cylindrical form seated within the neck, the cap having an opening in its top, a stack fitted in said opening and upstanding from the cap, a manually operable damper in said stack, a partition within the chamber above at the bottom thereof and formed with openings,

a burner within the chamber and arranged above and in spaced relation to the partition, the Wall of the chamber below the partition being formed with openings for the admission of warmed air into the portion of the chamber below the partition and the circulation of the air currents up through the openings in the partition and finally through the stack, the cap having an opening therein at one side of m the stack whereby the flame of the burner may be viewed, and a closure plate swivelled upon the top of the cap and movable into and out of position to close said last named opening. In testimony whereof I affix my signature.
